Renewables-powered high temperature heat pumps are cheapest option for industrial steam

New research from Austria has compared different industrial heat-generating techniques and has found that wind or solar-powered heat pumps are the cheapest and most environment-friendly solution.A research team at the Johannes Kepler University Linz in Austria has suggested that policymakers subsidize industrial projects using heat pumps to generate steam with a tariff of €3 ($3.2) per gigajoule (GJ). That is the result of a pricing analysis of the environmental impact of different steam techniques, which found heat pumps working with renewable energy to be the least costly. "Taking into account ...
